First, thanks for all the wonderful help during this course of Real Analysis! This website is amazing!
I have to determine whether the series: 1 - 1/2 -1/3 + 1/4 + 1/5 - 1/6 -1/7 + 1/8 + 1/9 - 1/10 - 1/11 ... converges or diverges
I assume I have to do a rearrangement to show this, but I don't know how.
Please, give me some hints
